Frederique Constant’s E-Strap Can Make Any Watch Smart

If you really like watches, you probably aren’t yet ready to give up your hard-won Rolex for a smartwatch just yet. What if your Rolex could double as a smartwatch? With the Frederique Constant E-Strap, it can do just that.

The Frédérique Constant Group, a firm that focuses on connected technology, recently launched their new E-Strap. Don’t have a Rolex? No problem as the E-Strap can turn your ordinary old watch into a smart, 21st-century watch.

This new leather watch strap has the potential to turn just about any watch into a sleep and fitness tracker. All of the electronics and sensors, including the accelerometer and battery, are located in the strap’s buckle rather than the watch case. Connected to the buckle of the strap is a tiny module that tracks fitness and sleep. The buckle module is so small that you can hardly even see it. It also weighs next to nothing.

The Frédérique Constant E-Strap is water resistant and charges through a tiny port located on the left-hand edge of the strap. According to Frédérique Constant, the charge lasts one week.

The strap works with an app that tracks your activity and sleep. It also offers tips and coaching to help you meet your wellness goals. The E-Strap has Bluetooth connectivity, and the app is compatible with both Android and iOS.

Available in black leather and two different shades of brown, this strap looks great with most watches. The buckle is available in either gold, stainless steel or rose gold colours.
